Ligma is a fictional disease that became a viral internet prank in mid-2018, famously associated with a hoax claiming the popular streamer Ninja had passed away from it. The joke functions as a setup-punchline trap similar to 'deez nuts,' where one person asks 'What's ligma?' and the other responds 'Ligma balls.' It skyrocketed in popularity on platforms like Twitter and Instagram, eventually evolving into more surreal iterations involving figures like Steve Jobs or Dr. House. The meme remains a staple of internet culture, frequently used to bait unsuspecting users into a classic wordplay trap that is both immature and undeniably iconic.
